This is the OB domain from 26S proteasome regulatory subunit 7 (PRS7, also known as PSMC2, Rpt1 or MSS1), a component of the 19S proteasome cap [1-5]. These are one of six ATPases of the regulatory particle that form a heterohexameric ring. This domain mediates interactions with USP14 or Ubp6 [2,4].
This domain is found at the N-terminus of the 26S proteasome regulatory subunits RPN1 (also known as 26S proteasome non-ATPase regulatory subunit 2 (PMSD2)[1]. The domain is formed by an array of alpha helices [2].

This is the C-terminal domain found in S. cerevisiae Rpn2 (26S proteasome regulatory subunit RPN2) as well as other eukaryotic species. A study revealed that the C-terminal 52 residues of the Rpn2 C-terminal domain are responsible for mediating interactions with the ubiquitin-binding subunit Rpn13. Futhermore, the extreme C-terminal 20 or 21 residues of Rpn2 (926-945 or 925-945) of S. cerevisiae, were shown to be equally effective at binding Rpn13. Multiple sequence alignments indicate that Rpn2 orthologs are highly conserved in this C-terminal region and share characteristic acidic, aromatic, and proline residues, suggesting a common function. In the structure of Rpn2 from S. cerevisiae , this region is exposed and disordered, and is thus accessible for associating with Rpn13. The Rpn2 binding surface of human Rpn13 has been mapped by nuclear magnetic resonance titration to one surface of its Pru domain [1].

This is the C-terminal domain of the 26S proteasome regulatory subunit RPN5 proteins.This helical domain can be found adjacent to Pfam:PF01399. The 26S proteasome is the major ATP-dependent protease in eukaryotes. Three subcomplexes form this degradation machine: the lid, the base, and the core. The helices found at the C terminus of each lid subunit form a helical bundle that directs the ordered self-assembly of the lid subcomplex. This domain which comprises the tail of RPN5 along with the tail of Rpn9, are important for Rpn12 binding to the lid [1].
